Biology is a diverse and rapidly expanding field of study that addresses issues relevant to health, agriculture, industry and the environment. Biologists are responsible for new discoveries in medicine and molecular biology, increasing crop yields and pest resistance, defining the ecological relationships that maintain our planet, and examining the origins and evolution of species, to name just a few.

You will learn and conduct research alongside our faculty, who are highly-regarded and internationally known for their discoveries. Beyond the classroom, we encourage students to seek out faculty mentors and to conduct research very early in their college careers. Not only does this provide you the opportunity to apply knowledge learned in the classroom, but it also establishes you in the field and paves the way for future success.

Our program is highly regarded by both employers and educational institutions, allowing our graduates to pursue careers in government, education, and industry. Many students go onto graduate or professional schools, such as medical, dental, podiatric medicine, optometry, veterinary medicine and pharmacy.
